About
A smart ring for people who want health data without sacrificing style or comfort. The Oura Ring 4 blends a sleek, all-titanium build with a discreet, screen-free profile that fits in anywhere, whether you’re at the gym, at work, or out for the night.
Inside, it tracks over 30 biometrics including sleep, activity, heart health, and stress, all powered by an adaptive Smart Sensing platform. Battery life stretches up to eight days, and the ring is water-resistant and lightweight, so you’ll barely notice it’s there.
The companion app delivers deep insights without overwhelming you, and syncing with Apple Health, Google Health Connect, and more is seamless. Sizing is unique, so the included sizing kit ensures a perfect fit. If you want a health tracker that doesn’t look like one, this is about as premium and understated as it gets.
